The passive house standard has long been implemented as a tried and tested benchmark for the construction of one-family houses and multi-family dwellings. However, there are comparatively few examples of the passive house standard being applied in larger building complexes. Three main principles serve as the underlying basis for the passive house concept: insulation against the loss of heat, air-tightedness, and controlled ventilation with heat recovery. The passive house standard is designed to achieve a higher level of building quality and greater user comfort with the least possible energy consumption and burden on the environment. ENERGYbase will serve as a reference project highlighting the compatibility of ecological and economic considerations in the construction of state-of-the-art commercial and office properties.
Energy of the future
One of the innovative features of ENERGYbase is the exclusive use of renewable energies. The passive house standard makes it possible to keep energy requirements at a particularly low level. The generated geothermal energy completely covers all heating and cooling needs. Furthermore, a 400m² photovoltaic facility located on the folded south facade of the building will also supply part of the total electricity requirements. The passive application of solar energy will also be implemented at ENERGYbase. An innovative ventilation concept enables the integration of solar energy in summertime by means of solar cooling (solar sorption supported air conditioning), as well as the use of plants to ensure ecologically-friendly, controlled humidification in winter.
ENERGYbase offers the highest available level of user comfort:
The use of plants as the basis for a natural air conditioning system ensures a particularly comfortable room climate in ENERGYbase, also during the winter months. In contrast, the air in typical office complexes is too dry due to intensive heating, resulting in throat and sinus infections as well as the threat of catching colds.
Optimal working conditions are a guarantee for the creativity, commitment and performance of employees. The particularly conducive room climate increases the feeling of workplace well being, preserves people’s health and thus serves as an important economic factor.
